A synthetic peptide that irreversibly inhibits caspase-2 and related caspase activity. The inhibitor is designed as a methyl ester to facilitate cell permeability. Ready-to-use caspase inhibitors that are synthesized using a patent-protected method. These inhibitors are cell-permeable and nontoxic. Caspase Inhibitor Sets in the ready-to-use format are also available, providing researchers with more convenient tools for studying multiple apoptosis-inhibiting processes. Sequence: Z-Val-Asp-Val-Ala-Asp-FMK (FMK, fluoromethyl ketone) Purity: ≥ 98% by HPLC analysis Concentration: 2mM
